This is one of my favorite weeknight dinners because it comes together in just 40 minutes total, and honestly, it feels fancy enough to impress guests. Sweet caramelized onions paired with tender roasted prawns create this incredible depth of flavor that tastes like you spent hours in the kitchen, but you didn't. The garlic gets wonderfully mellow and sweet as it roasts, while fresh lemon juice and thyme brighten everything up. Prawns are packed with protein and selenium, which is wonderful for your immune system, making this both delicious and nutritious. It's simple, elegant, and genuinely one of those dishes that reminds you why you love cooking at home.

Instructions
- 1
Preheat your oven to 425°F (220°C). Pat the prawns dry with paper towels and season both sides with salt, pepper, and red pepper flakes.
Tip: Dry prawns will roast better and develop a better golden crust.
- 2
Heat 2 tablespoons of olive oil in a large oven-safe skillet over medium heat. Add the sliced onions and cook, stirring occasionally, for 8-10 minutes until they become soft and begin to caramelize.
Tip: Don't rush the onions—allow them time to develop their natural sweetness.
- 3
Push the caramelized onions to the sides of the skillet. Add the remaining 2 tablespoons of olive oil and butter to the center, then add the minced garlic and cook for 30 seconds until fragrant.
Tip: Keep the garlic away from direct high heat to prevent burning.
- 4
Arrange the seasoned prawns in a single layer throughout the skillet, nestling them among the onions. Pour the white wine and lemon juice over the prawns.
Tip: Work quickly so the onions don't cool down significantly.
- 5
Sprinkle the fresh thyme over the top and transfer the entire skillet to the preheated oven.
Tip: Make sure your skillet has an oven-safe handle before transferring.
- 6
Roast for 8-12 minutes, depending on the size of your prawns, until they turn pink and opaque throughout. The prawns are done when they curl slightly and feel firm to the touch.
Tip: Check at 8 minutes—overcooked prawns become rubbery.
- 7
Remove from the oven and taste the onion mixture, adjusting seasoning if needed. Divide the roasted prawns and caramelized onions among four plates.
Tip: Spoon some of the pan juices over each serving.
- 8
Garnish with fresh chopped parsley and serve immediately with crusty bread or over rice.
Tip: The cooking juices are flavorful—don't waste them!

Beergarita
My go to drink for summer gatherings is this refreshing Beergarita, and let me tell you, it's a total crowd pleaser. The combination of tequila, triple sec, fresh lime juice, and a cold Corona creates something that tastes way more complicated than it actually is. Lime juice is packed with vitamin C, which is great for your immune system, and the whole thing takes just five minutes to throw together. Best part? It's incredibly budget friendly since you're probably already stocking most of these ingredients anyway.
Tropical Quinoa
This tropical quinoa bowl has become my go to weeknight dinner because it comes together in just forty minutes and tastes like a mini vacation on a plate. Quinoa is one of my favorite ingredients since it's a complete protein with all nine essential amino acids, making it so satisfying and perfect for keeping energy levels steady. The combination of papaya, red bell pepper, and fresh cilantro brings vibrant flavors and colors, while the rice wine vinegar and orange zest add just the right brightness. Best part is the ingredient list is simple and affordable, yet feels fancy enough to impress anyone at your table.

This is one of my favorite quick weeknight dinners because it comes together in just ten minutes flat.

The seabass gets beautifully golden and flaky while the freekeh provides substantial whole grains packed with fiber and protein.
